For special customer request it is possible to produce switches with different switching programs and without mechanical interlock.
It is recommended that TS35 rail, on which the switch will be mounted, is installed on supports (not directly on the base).
Switches of SK100 Series (for building in), mounted on a rail with the knob on the door are intended for 0-I disconnector programs with knob switching angle equal to 90° e.g. SK100/2.423-D100ZC.
Disconnectors 0-I for building in in a switching cabinet with switching angle of 90° are additionally fitted with a mechanical lock which prevents the door from opening when the actuator (knob) is in ON position.
